Our teams report that the migrants they treat—especially women and children—often have limited access to basic services and spend long periods in unsanitary, hostile environments. These conditions worsen medical issues such as respiratory infections, skin diseases, post-traumatic stress disorder (PTSD), and other mental health problems linked to exposure to extreme violence.
Despite these conditions, Mexico remains a key transit and destination country. Requests for asylum in Mexico increased exponentially in the past decade, reaching 86,000 in 2024. However, asylum seekers were just a fraction of the total number of migrants traveling through Mexico, many of whom aimed to reach the United States. According to official statistics, between January and August 2024, there were 925,000 people on the move in the country. However, migratory flows have since decreased in some areas such as Tamaulipas state, resulting in MSF concluding projects in Reynosa and Matamoros on September 30, 2025.
